Sensi flex, flex 100= stiff
F2p, flex 50= flex
I haven't hit either of them enough to say so definitively. I had a 18 asa dc and put just a handful of swings on it when it came out and just last week i started to put some swings on my 18 bb legit so as i said can't say for sure with the time lapse between the twoDo you think the feedback felt in the handle upon contact feels pretty much the same between both manufacturers?
